Yes you can. Our recommendation is to first paint the frame in a light grey or similar color acrylic, then paint the Glamour Dust Glitter over it to create more depth and "pop". You may need to apply two coats for solid coverage. -DecoArt Paint Guru
Hi Karyn, Unfortunately, the answer is no. The grout material is too heavy and thick and will completely cover up the small flake glitter in the paint and you won't get the shimmer effect you're looking for if you mix it. -DecoArt Paint Guru
Mimi, We would not recommend adding this to a standard latex broadwall paint. The yellow paint will saturate the base to the Glamour Dust paint ,mask the glitter and will not be visible in the finished product. DecoArt Paint Guru
The kind of brush would just depend on your project.
Dee, Since our paints are water-based and non-toxic, it is safe to use for this application. However, it was not formulated for this type of use and will dry permanent and would require a sealer over the paint to protect it from normal use and moisture exposure. -DecoArt Paint Guru
I don't think this product would meet your needs.
This could be used in that manner.
